  6. 6. A. Stage one: <br />1.1 Calcareous and Argillaceous<br />- Calcareous : limestone , marl , chalk<br />- Argillaceous : silicates of alumina<br />1.2 Preliminary crushing<br />- Crushing <br />1.3 Fine grinding mills<br />- Grinding<br />
  7. 7. B. Stage two : <br />2.1 The elevators<br /><ul><li>lime slurry and clay slurry
  8. 8. correction silos</li></ul>2.2 Correction silos<br />- ratio of the components<br />
  9. 9. C. Stage three: <br />3.1 Rotary kiln<br />- Dried Clinker<br />- 1400 - 1500 c<br />
  10. 10. D. Stage four: <br />4.1 Elevator clinker storage<br />- Storage in the huge tank <br />4.2 Adding gypsum<br />- Purpose : protect clinker <br />97% clinker 3% gypsum<br />95% clinker 5% gypsum<br />4.3 Grinding<br />- Powdering the cement<br />
  11. 11. E. Stage five : <br />5.1 Elevator cement silos<br />- Storage <br />5.2 Weighing and packing<br />- Packing in 50kg bags <br />- Re-weighting <br />5.3 Supply<br />- giving out to the companies<br />
